The Thunder Letter was an electronic newsletter published irregularly by the
Unlimited Racing Commission/Hydros from 1995 to about 1998. A few issues were
produced after that. Nearly 400 issues were published. An archive of the issues
had once been available on the late Hydros website but its successor, the
Hydro/PROP website does not feature it. I hope to mount the archive of the
Thunder Letter on the Hydroplane History website in the near future. --LF
